I can do the switch on an Atomic in 15 seconds, once it's in the vise and I have my large wrench in hand.I've got a DIN Adaptor for my Oceanic Delta Reg, and it takes a standard sized wrench (I forget exact size - maybe 3/16 - but there is one on my Diver's Multi-Tool) and about 45 seconds to switch out from Yoke to DIN or back.

True, but for me, who doesn't even own a vise let along a workbench, it required taking everything to a friend's garage. I switched mine over to yoke when I got sick of lugging a DIN adapter on warm water trips (I was mainly diving cold water at the time using DIN-valved HP tanks). Since the switch to yoke, I never switched back - the friend with the vise moved out of state. Figured it was easier to just give up cold water divingSwitching from yoke to DIN or the other direction would likely be the sort of thing one would do at home before a dive trip
